Lytro camera

Is it too much of a stretch to call Lytro's light-field photography technology the future of cameras? Perhaps not. Designed so that its sensors take in light from multiple directions, the Lytro camera is able to capture all of this directional information so that users can take advantage of after-the-shot computing to convert it into imagery our eyes can process.

What that means is that Lytro cameras can shoot a 3D image of whatever is in front of it, allowing photographers -- and anyone who comes across a Web-based Lytro photo -- to choose what in the photograph to focus on.
